If a wave has a wavelength of 0.5 m and a frequency of 2134 Hz, what is its speed? *SHOW ALL 4 STEPS.

nexus9112 [7]

<h3>given:</h3>

wave length= 0.5 m

frequency= 2134 Hz

the speed

<h3>solution:</h3>

$v = f \gamma$

$v = velocity$

$f = frequency$

$\gamma = wave \: length$

$v = 2134 \times 0.5$

$v = 1067s$

hence, the speed of the wave is 1067s.

Find the volume of the solid generated by revolving the region bounded by the graphs of the equations and inequalities about the

I am Lyosha [343]

Answer:

The Volume of the solid

V = π(1365.33) cubic units

Step-by-step explanation:

Step(I):-

Given curves are x²- y² = 64 , x=0 , y=-8 and y=8

The given function x = f(y)

x²- y² = 64

x² = y² +64

The Volume of the solid generating by revolving the region bounded by the graphs of the equations

$V = \pi \int\limits^a_b {x^2} \, dx$

Step(ii):-

the limits are y = a = -8 and y = b=8

The Volume of the solid

$V =\pi \int\limits^8_8 {(y^2+64)} \, dx$

$V = \pi (\frac{y^{3} }{3} + 64 y )_{-8} ^{8}$

$V = \pi (\frac{(8)^{3} }{3} + 64 (8) - (\frac{(-8)^{3} }{3} +64(-8) )$

$V = \pi (\frac{(8)^{3} }{3} + 64 (8) - (\frac{(-8)^{3} }{3} +64(-8) ) = \pi (\frac{1024}{3} + 1024)$

V = π(1365.33) cubic units

The interquartile range is used as a measure of variability to overcome what difficulty of the range?

notsponge [240]

Answers b and c are 'way off (wrong). Answer d is not negative, and thus could not be the correct answer. That leaves Answer a: the range is influenced too much by extreme values.
